LC89057W-VF4A-E

Ordering number : EN7202A LC89057W-VF4A-E CMOS IC LC89057W-VF4A-E 2.2 Outputs various information to make system configuration easy Outputs DTS-CD/LD detection flag by DTS sync signal detection. Outputs burst preamble Pc from microcontroller interface. Calculates sampling frequency of input signal and outputs it from microcontroller interface. Outputs interrupt signal for microcontroller (interrupt source can be selected). Outputs signal of transitional period switching between VCO clock and oscillation amplifier clock. Outputs bit 1 of channel status (non-PCM data detection bit). Outputs emphasis information of channel status. Outputs renewed flag of the first 48 bits channel status. Channel status bit, validity flag and user data output are selectable. Outputs modulation/demodulation preamble B information. Possible to carry out and output various settings through microcontroller interface. 2.3 Plenty of built-in functions to reduce peripheral circuits Includes modulation function that can attach channel status, validity flag, and user data. Equipped with a total of 7 digital data input pins: 1 input pin with an amplifier and 6 input pins with 5V tolerable TTL level signal. Possible to monitor input pin status with microcontroller by mounting a bi-phase input data detection function. Possible to select input data among 8 system input data including modulation function output. Possible to select output of input-data through among 8 system input data aside from selecting demodulation data. Includes 2 system bit clock and LR clock outputs. Various frequency-dividing ratios can be set to one of these two systems. Equipped with a serial digital audio data input pin. Possible to switch with demodulation output. Possible to modulate the data that is input to the serial digital audio data input pin. Includes built-in oscillation amplifier and frequency divider for quartz resonator and also possible to use them as clock generator. Includes 4 bits general-purpose parallel I/O port. It can be used for interface with peripheral ICs. All the channel status can be decoded through peripheral circuit using preamble B information. A continuous switching operation between external clock synchronous mode and PLL clock synchronous mode is possible. Single 3.3V-power supply operation. TTL input port supports 5V interface. Adopts small SQFP48 package for efficient use of substrate mounting area.
